Answer:
32 possible combination of chromosome
Explanation:
According to the law of independent assortment as proposed by Mendel, alleles of a gene will separate into gamete independently of the alleles of another gene. Since this organism contains 10 chromosomes in its somatic cell, it will undergo meiosis to produce half number of chromosomes in its gametes i.e. 5 chromosomes.
If we know the haploid number of chromosomes of an organism i.e. n, we can calculate the possible combination of chromosomes that will be present in its gametes as a result of independent assortment during meiosis using the formula:
2^n, where n= haploid no. of chromosome
If n is 5 chromosome in this case, the possible combination of chromosome in its gametes will be 2^5 = 32. Hence, as a result of independent assortment, an organism with 10 chromosome in its somatic cell will produce 32 possible combinations of chromosome in its gametes.

Which form of hypoxia reflects poor O2 delivery resulting from too few RBCs or from RBCs that contain abnormal or too little hemoglobin?
a. hypoxemic hypoxia
b. ischemic (stagnant) hypoxia
c. anemic hypoxiad. histotoxic hypoxia
Answer:
c. Anemic hypoxia
Explanation:
Hypoxia is a health condition in which the body or a region of the body is not adequately supply with oxygen at the tissue level. Types of hypoxia include:
Hypoxemic hypoxia is a condition in which their is low level of oxygen in blood in the arteries due to the inability of the lungs to properly oxygenate blood.
Ischemic (stagnant) hypoxia is a type of hypoxia that occurs due to a decrease in blood flow preventing adequate blood supply to tissues.
Anemic hypoxia occurs when the ability of the blood to carry oxyegen is reduced due fewer red blood cells or red blood cells that contain little or abnormal hemoglobin molecules hemoglobin molecules.
Histotoxic hypoxia is hypoxia in which the cells are unable to use oxygen from the bloodstream, even though there is normal delivery of oxygen to such cells and tissues. This is due to the poisoning of the cells or tissues causing a disruption in their respiratory mechanism, for example in Cyanide poisoning.
Therefore, the correct answer is anemic hypoxia.

You are the lucky student of a wacky professor who develops a time machine. He asks if you will test it with him. You get in and there is an immediate glitch–the date readout fails so that when you land you are not sure what era you are in. As your time machine lands, you see an unusual landscape before you. As you open the door you realize you cannot breathe. You quickly shut the door, realizing you are in the _____.
1) Archaean eon
2) Cambrian period
3) Cenozoic era
4) Mesozoic era
Answer: Option 1 is the correct answer
Archaean eon
Explanation:
You are in the Archean Eon era because the it was early in the Archean that life first appeared on Earth. The most two earlier of the formal divisions of Precambrian time (about 4.6 billion to 541 million years ago) and the period when life first formed on Earth It began about 4 billion years ago with the formation of Earth’s crust and enlongated to the begining of the Proterozoic Eon 2.5 billion years ago; the latter is the second formal division of Precambrian time.
In the Archean eon there are unsual landscapes no rocks are preserved from this stage. The earliest terrestrial materials are not rocks but minerals.
Throughout the Archean, oceanic and island arc crust was produced semi-half way.
You cannot breathe because there was no oxygen on the Earth. Oxygen was only present in compounds such as water and chemical reactions change to carbon containing molecules that form simple living cells that does not require oxygen.

Why did the author think e-skin could make better hearing aids? In your answer, explain how the ears connect to the nervous system
Answer:
The author thought this because e-skin might hold promise for use in soft, wearable hearing aids. Unlike conventional aids, soft devices are more comfortable because they mold to human skin. When the ear receives sound vibrations, there are hair cells in the cochlea that vibrate and translate the sounds into electrical signals. These electrical signals are transmitted to the auditory nerve, which transmits the information to the brain.
Answer:
Sound is one of the five major senses. The nervous system carries sound signals from sensory receptors to the brain. E-skin has many sensory receptors that can carry signals toward the brain, enabling us to react to sounds. Because e-skin is soft, scientists can use it to make effective hearing aids that are quite comfortable to wear.

What are two ways the excretory system helps the body maintain homeostasis?
Answer:
1.Osmoregulation
2.Thermoregulation
Explanation:
1.Osmoregulation is the maintenance of constant amount of water in the body of an organism.The kidney is responsible for this phenomenon as in it has a nephron in which at a particular part of the nephron,i.e the conducting tube which sites a hormone called the anti diuretic hormone which makes the walls of the conducting tube permeable to allow the movement of water from the urea back into the body before it is transferred into the bladder for to be released into the external environment.
2.Thermoregulation involves the maintenance of heat in the body of an organism.The skin is responsible for this process.It has hairs which lie on the surface of the skin to loose heat to the external environment during the hot days and also stands on the surface of the skin which trap a film of air on the skin surface to prevent heat loss in the cold days.
I HOPE IT'S OK?
Answer:
The kidneys control the amount of water, ions, and other substances in the blood by excreting more or less of them in urine. The kidneys also secrete hormones that help maintain homeostasis.

If a cell has 24 pairs of chromosomes in its diploid state, how many
chromosomes will it have after Meiosis 2?
A. 12
B. 24
C.48
D. 6
Answer:
option A is correct that is 12
Explanation:
meiosis occur in two phases in first phase DNA replication occur and amount of DNA become doubled without any change in the chromosome number and two daughter cell (each 2 n)are formed.
now in stage 2 each daughter cell undergoes mitosis with the formation of two cells with half chromosomes(n)
now 2n=24
n=24/2 =12
after meiosis stage 1...........two daughter cell each with 24 chromosomes
stage 2 .............each daughter cell form two grand daughter cell each with 12 chromosomes
net result.......4 daughter cell each with 12 chromosome(assuming cell as a diploid cell)
If a cell has 24 chromosomes before cell division then the daughter cell resulting from the mitotic division will have 24 chromosomes while the daughter cell resulting from the meiotic division will contain 12 chromosomes each.
The answer is option A.
What are meiotic and mitotic cell divisions?There are sorts of cell departments: mitosis and meiosis. most of the time whilst humans discuss “cellular division,” they suggest mitosis, the procedure of making new frame cells. Meiosis is the sort of cell division that creates egg and sperm cells. Mitosis is an essential technique for lifestyles.

11. The governments of many countries have regulations
that are designed to prevent the accidental
introduction of nonnative insects into their countries.
This is because, in these new habitats, the nonnative
insects might
1) become food for birds
2) not survive a cold winter
3) not have natural predators
4) add to the biodiversity
Answer:
The answer is 3. Not have natural predators.
Explanation:
Nonnative insects in new habitats mean that there are no predators there that eat them. This means that choice 1 will be eliminated. Now choice 2 also isn't it since if the insects do not survive a cold winter, there wouldn't be any nonnative insects in the habitats, causing no need to have strict regulations. Between choices 3 and 4, 4 doesn't make any sense. If it adds to a habitat's biodiversity, the ecosystem will benefit from it. However, the nonnative insects will harm the ecosystem, causing choice 4 to be eliminated. This means that only choice 3 is left. Choice 3 also makes sense since the nonnative species are also invasive species, having no natural predators in the new habitat. So, the answer is 3. Not have natural predators.
The permeability of ______ in the second coiled tubule of the nephron is controlled by _______.
Answer:
distal tubule, the concentration of ADH
Explanation:
Nephron is the functional unit of kidney. Nephron undergo reabsorption and secretion along different part.
The permeability of distal tubule to water in the second coiled tubule of the nephron is controlled by the concentration of ADH. The concentartion of ADH controls the degree of dilution or urine concentration. High ADH level makes , tubules permeable to water while the absence of ADH makes them impermeable to water.
Hence, the correct answers for blanks are distal tubule and the concentration of ADH.
Answer:
The distal tubule, the concentration of ADH.
True or False: Within the body, all atoms combine to form molecules. If false, why?
Answer:
True
Explanation:
Two or more atoms combine to form a molecule, like how the water molecules, proteins, and sugars are found in living things.
Hope this helps! （づ￣3￣）づ╭❤～
The statement i.e. ''Within the body, all atoms combine to form molecules'' is true.
Atoms combine together to form molecules because atom is unstable substance which can't stay in single form due to its reactive nature but become stable when they form molecules due to filling of outermost shell and attain the electronic configuration of noble gases so we can say that atoms formed molecules in order to attain stability and can not remain individually.

When CFCs are exposed to high levels of UV radiation, what occurs? A. The compound breaks down into nitric oxide and ozone. B. All of these C. A chlorine breaks off and forms a free radical. D. They become ionized and stick together in clumps that become part of smog.
Answer:
C. A chlorine breaks off and forms a free radical
Explanation:
When CFCs are exposed to high levels of UV radiation in the atmosphere, the CFC molecule breaks into chlorine and forms free radicals.
These free chlorine radicals then reacts with ozone molecules and breaks the ozone atom (O3) to form chlorine monoxide and oxygen (O2) molecule.
CFCs are main cause of ozone depletion in the atmosphere.
Hence, the correct option is "C".
If capeland switches from producing 0 watermelons to producing 18 million tons of watermelons, what does it give up?
Answer:
Attached to this solution is an image of the complete question and data.
The correct answer is:
6 million pairs of shoes
Explanation:
From the diagram attached to this answer, the following data can be gotten:
Watermelons shoes
(Millions of tonnes) (Millions of pairs)
0 15
8 14
14 12
18 9
20 5
21 0
From the pattern of the data shown above, we notice that as the production of one commodity increases, the other is given up (decreases)
Therefore, to find how much shoes are given up if Capeland switches from 0 watermelons to 18 million tons of watermelon, we will find the difference between the number of shoes produced at 0 and at 18 million tons of watermelon
at 0 watermelon; shoes = 15 million pairs
at 18 million tons of watermelon; shoes = 9 million pairs
Therefore, number of shoes given up = 15 - 9 = 6 million pairs
Hence, 6 million pairs of shoes are given up tp increase production of watermelon from 0 to 18 million tons

Without the discovery of magnetic reversals recorded on the ocean floor, scientists
A. could not confirm the usefulness of sonar
B. could destroy the hypothesis of continental drift
C. could not provide a mechanism for moving continents
D. could explain how the seafloor was being destroyed
Answer:
C. could not provide a mechanism for moving continents
Explanation:
Without the discovery of magnetic reversals recorded on the ocean floor, scientists could not provide a mechanism for moving continents.
Magnetic reversals are responsible for geological shifts and depend on the distribution of tectonic plates that causes movements of continents.
Asymmetric movement of tectonic plates leads to movement of continents and the degree of asymmetry varies with the same rythm of the magnetic reversal rate.
Hence, discovery of magnetic reversals are important to identify the mechanism for moving continents.
The study of a living being is called biology.
The correct answer is C.

Tara placed a grape in a solution, after sometime she noticed that the grape started to shrink.
a. Name the solution and explain.
b. Then Tara placed the raisin in a solution and noticed it started to swell up. Name the solution and explain
Answer:
a. Hypertonic solution
b. Hypotonic solution
Explanation:
There are basically 3 types of solutions in biology,
1) Isotonic-Same concentration of solute and solvent inside the grape and in the solution.
2)Hypotonic solution-More concentration of solvent in the solution than in the grape.
3)Hypertonic solution-More concentration of solvent in the grape than in the solution.
Now,
a. Tara had kept the grape in a hypertonic solution. The solvent will start draining from the grape to equalize the concentrations of solvent inside and outside. So, the grape shrank due to loss of water.
b. Tara kept it in a hypotonic solution. The solvent will start entering the grape to equalize the concentrations of solvent. So, the grape started swelling.
